RE: webtv-ISSUE-18 (JanL): Video tag support of MPEG2-TS [HOME_NETWORK_TF]

Hello Jean-Claude,

When I created the use case I referred to MPEG2-TS in a broad form so it can be carried over broadcast (DVB-S, DVB-T or DVB-C) or broadband (IGMP, RTSP or HTTP).

I do not see the correltation of the adaptive streaming since adaptive streaming works on a manifest which is provided prior to the actual streaming. The implementation issues listed in teh use case relate to the actual stream and information provided within MPEG2-TS or even other encapsulation protocols (ex. MP4).

As to how this applies to HNTF I take it up in a seperate e-mail thread.

Best Regards,

I am not sure I understand your request here, Jan.
If you mean MPEG-2 TS in broadcast, the issue is with standards like OIPF and HbbTV (video/broadcast object), or in HTML5 directly maybe.
If you mean MPEG-2 TS in broadband, the issue is probably with 3GPP AHS or MPEG DASH.
How is it a problem for the Home Network Task Force ?
Best regards

While video tag support many of the indicated implementation requirements not all are supported. This use case may not explicitly indicate the missing portions but highlights the full set of implementation requirements.
